Obtruders are individuals who impose themselves or their opinions on others. To describe such people, a variety of synonyms are available. An aggressive obtruder can be called a bully, while a persistent one may be referred to as insistent or importunate. Those who are pushy or overbearing might be described as assertive or forceful. A meddler is someone who interferes in the affairs of others, often without their permission. Nosy or inquisitive individuals might be described as nosy parkers, busybodies, or pry-mongers. Regardless of the term used, dealing with obtruders can be challenging, but it is essential to set boundaries and communicate assertively to protect oneself from unwarranted intrusion.
